Your question isnt clear.
In FY2010 MS will be around $1B in profit in the EDD division (Xbox 360) if not more. Already is at $660M profit through the 1st 2 quarters. Previous 2 Fiscal Years EDD was profitable about $570 million.
If your asking will the whole Xbox 360 initiative from beginning then no. That will take some more time EDD lost about $3B the 1st 2 years (1B of that was the money set aside to handle future RRoD repairs).
And of course MS is hugely profitable.
Its libraries that sell systems not a single game.
